Application vfiled April 21, 1908. Serial No. 428,429.

To all whom it may concern:

Be it known that I, JOHN LJUNG, a citizen of the United States, residingat Alexandria, in the county of Douglas and State of Minne- Sota, haveinvented a new and useful Saw- Vise, of which the following is aspecification.

'lhe invention relates to improvements in saw vises.

The object of the present invention is to improve the construction ofsaw vises, and to provide a simple, inexpensive and etti cient one ofgreat strength and durability, adapted to clamp. uniformly throughoutits length either narrow 'or wide bladed saws without ermitting one endof a saw blade to vibrate oosely within it when the teeth of the saw arebeing filed.

Another object of the invention is to provide a saw vise having apivotally mounted saw clamp, adapted to be arranged at difierent anglesor inclinations andl secured in its adjustment by the means forattaching it to a bench or other sup ort.

With these and ot er objects in view, the invention consists in theconstruction and novel combination of parts hereinafter fully described,illustrated 1n the accompanying drawings, and pointed out in the claimshereto aplpended; 1t being understood that various c anges in the form,proportion, size and minor details of constructlon, within the scope ofthe claims, may be resorted to without departing from the spirit orsacrificing an f of the advantages' of the invention.v

n the drawings:-Figure 1 isa perspective view of a saw vise, constructedin accordance with this invention. Fig. 2 is a side elevation, showingthe o posite side of the saw vise. Fig. 3 is a si e elevation of thesaw. vise, illustrating the manner of clamping a wide bladed saw. Fig. 4is a vertical sectional view on the line 4-4 of Fig. Fig. 5 is ahorizontal sectional view on the line 5-5 of Fig. 3. Fig. 6 is a detailpersppctive view of the angle locking lever.

L1 e numerals of reference designate corresponding parts in all thefigures of the drawmes.

tThe saw vise includes a saw clamp rovided width a horizontal pbivot 1,ada te to ermit the saw clamp to e arrange Aat diferent angles andinclinations, and supported by a bench clamp, composed of an upperstraight horizontal member 2 and a substantially L-shaped member 3,consisting of a vertical arm or portion and a horizontal arm or portion.The upper horizontal member is provided at one end with a jaw 4 forengaging the upper face of a bench 5, or other suitable support, and theother end of the member 2 is provided with a slot or bifurcation 6,which receives the upper end of the vertical portion of the L-s iapedmember. The upper end of the vertical portion of the L-shaped member 3and the bifurcated end of the horizontal member 2 are provided withregistering openings for the reception of the pivot 1. The lowerhorizontal arm of the L-shaped member is provided with a threadedopening 7 for the reception of a clamp or tiumb screw 8, pivotallyconnected at its upper end to a horizontal jaw 9 for engaging the lowerface of the bench 5. The lower end of the screw 8 is provided with asuitable head for enabling it to b'e readily grasped and operated. TheL- shaped member is provided at the upper end or portion of itsvvertical arm with opposite shoulders 10, and the sides of thebifurcation 6 have straightedges 11, which engage the shoulders .10,whereby when pressure 1s applied byA the screw 8, pressure will betransmitted to the pivot 1, 'which will be frictionally clamped by themembers 2 and 3 of the bench clamp with suflicient force to hold the sawclamp 1n its adjustment.

The saw clamp is provided with a substantiallyU-sha edbod 12,havingoneofits arms extended a ove t e other and carrying a relatively xed jaw 13,formed integral with the U-shaped body of the clamp. The jaw 13 isV-shaped 1n cross sectlon and cooperates With a corresponding V-shapedjaw 14, arranged in substantial parallelism with the jaw 13 and adaptedto :fit within the same, as clearly shown in Figs. 1 and 2 of thedrawings to clamp a narrow saw blade. When it is desired to clamp a keyhole saw, or similar narrow bladed saw, the ljaws are arranged withtheir outer cooperating portions m vertical planes. The U-sliaped bodyportion is arranged at an inclination, when the outer engaging portionsof the jaws 13 and 14 are vertical. When it is desired to clamp a wideblad'ed saw, such as a'n ordinary carpenters saw, the body portion oi'the saw clamp is arranged in a vertical position and the 'aws are movedbeyond an intertting position to provide aclear space between them, asshown in Fig. 3 of the drawings. This brings the wings or sides of theV-shaped jaws in an inclined position, the relatively fixed jawpresenting two engaging edges to the saw blade, and the movable jawpresenting a single engaging edge located at an intermediate pointbetween the upper and lower engaging edges of the fixed jaw.- lllhen thesaw clamp is arranged in this position, it is' adapt-ed to accommodate awide blade, which may extend into the space between the sides of theU-shaped body 12.

The movable or adjustable aw 14 is formed integral with a central sliank15,pivoted at an intermediate point to the upper end oiI the short sideof the U-shaped body by a boltI 16, or other suitable fastening deviceand forming a lever. The lever formed by the shank has a short upper armand a long lower or depending arm, which is adapted to be engaged by anangle looking lever 17. The angle locking lever 17, which consists cl' aShort arin 18, arranged at an angle to the lon arm, is fulcruined at itsangle on the body 12 at the bottom thereoiI by means ol' a bolt 19, orother suitable pivot. The body is provided at its lower portion with aboss 2U, which spaces the angle locking lever from the body to provide aspace for the shank or lever oi' the adjustable jaw. The lower ordepending arm ofv the shank or lever 15 is provided at its lower portionwith a notch 21, located at the inner edge oi' the shank and adapted tobe engaged by studs 22 and 23. The stud 23 projects from the inner faceof the long arm of the angle locking lever, and is adapted to engage thesaid notch 21 when the jaws 13 and 14 engage a saw having a wide blade.The other stud 22, which is located a greater distance `from the pivot19 than the stud 22, projects from the inner face oil the short arm 18of the locking lever and engages the recess or notch 21, when the jaws13 and 14 are arranged i'or clam ing a narrow saw blade. The lower armo` the shank or lever 15 is also provided with a sto 24, consisting of astud and arranged 'to e engaged by thelocling lever to limit the upwardswing oi' the long arm of the same.

The jaws, whether engaging a wide saw blade or a narrow saw blade, fitagainst the same and uniformly clamp the saw blades throughout theirentirey length so that one end or portion oi' the saw blade will not beleft free and permitted to vibrate when the saw teeth are led. The,pivotal movement oi" the saw clamp enables the angular or Vfshaped jawsto be arranged forrholding either a wide or narrow blade in a verticalposition and by tightening the screw 8, suHicient pressure is producedon the pivot 1 of the saw clamp to hold the latter in its adjustmentwhile the saw teeth are being led.

Having thus fully described my invention,- what l claim as new anddesire to secure by Letters Patent, is

1. A saw vise including a saw clamp provided with a pivot, and a benchclamp composed of two members connected togetherv by the said pivot andhaving means l'or engaging each other, and adjusting means carried byone oil the clamp members and cooperating with the. other to engage abench ci' support and adapted also to )roducc ressui'e on the pivot forholding t e sawc amp in its pivota adjustment.
